IMPROVEMENT IN WRITING-PENS- Specification forming part of LettersPatent No. 1 84,319, dated November 14, 1876; application filed ISeptember 10, 1875. v

To all whom it may concern:

Be it known that I, LEOPOLD BERAL BER.- TRAM, of 4 Park Road, NewWandsworth, in the county 'of Surrey, England, have invented certain newand useful Improvements in Writing and Drawing Pens, for dispensing withthe necessity of using liquid ink, as at present,'of which the followingis a specification:

This invention consists in adapting to writing and drawing pens awriting composition, so that it will only be necessary to dip the pen inwater, or other liquid, in order to pro duce ink in the pen.

The following is an. example of my said-invention as applied towriting-pens, reference being had to the illustrative sheet of drawinghereunto annexed.

Figure 1 is an elevation, Fig. 2 an underside view, Fig. 3a top view,and Fig. 4 a section through the line A B of Fig. 1, of a penconstructed according to my said invention, and ready to receive acartridge or cylinder containing the solid or concentrated ink, or othersuitable solid or concentrated writing composition of any desired color,soluble in water. Fig. 5 is an elevation, and Fig. 6 a top view, of acartridge or cylinder in which I place the concentrated ink.

This cartridge is cylindrical at a and cut away at b, so as to exposethe solid ink. I introduce the cartridge in the barrel of the pen at 0,Figs. 1 and 2, the projection d entering into the slot 0, thus keepingthe cartridge in its place. The pen furnished with the cartridge isshown in plan and elevation at Figs. 7 and 8.

For using a pen thus constructed it is simply necessary to dip the nibin water, which will dissolve a portion of the solid ink, causing it torun down the nib ready for use.

- A pen constructed as above will contain a quantity of solid ink,sufiicient to last for some time, and when exhausted a fresh cartridgecan easily he slipped into the barrel.

. I claim as my invention A pen constructed with a barrel, 0, adapted tocontain a cartridge, a, containing solid or concentrated ink or writingcomposition, sub stantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
